Connecting each device via a USB cable creates a mess of wires out the back of the frame.

The unga bunga way around that is some kind of bulky shroud that conceals them.

Instead I'm going to see if I can incorporate pogo pin connectors to the rail ends and modules.

I ordered these 4-pin pairs on AliExpress, which have PH2.0 plugs on the wire ends.

At the frame side, a short USB male to PH2.0 female adapter should be fine, and makes replacing them easy if I need to later on.

For the module end, I'll do the same but in reverse: PH2.0 female to USB A female, then very short (probably custom) relevant USB cables as required for whatever devices.

The modules that only need 2.0 USB so far are:

• VFD panel
• USB DAC/AMP
• Easy-access USB port
• Power for LCD (I've also found this HDMI magnetic pogo pin connector which could be added too in a set position)
